Dual Long-Throw Drivers

To get big bass, you need to move lots of air. That’s why every DS subwoofer comes with a Sunfire-designed, long throw woofer and an acoustically matched passive radiator. Move twice the air, get twice the bass – and from the same amount of space!

Sunfire Class-D Amplifier

Like many siblings, the DS line has taken the lessons learned from its older brothers and sisters –reinvented them, and called them its own. Take for example Sunfire’s classic approach to high-efficiency, high-output power supply design. The DS subwoofers are the first in the family to feature Class-D amplification, while sharing many of the same benefits as their higher-end counterparts. This approach dynamically adjusts the output of the subwoofer’s power supply to suit the requirements of the incoming audio signal, while keeping the form factor extremely compact – a hallmark of Sunfire engineering.
